Comic Books

In a Simpsons ComicsElseworld story, Homer was working for the Mafia, Comic Book Guy was the local don, and Lou and Eddie were his two flunkies. CBG assigned Homer to kill Milhouse, to which Homer remarked "Don't worry, boss. This little weiner is toast". CBG replied "Good. And please don't mix metaphors. You know it makes Lou nervous".

Film

From Hot Shots Part Deux: "Looks like the upper hand is on the other foot!"

Similarly, from The Naked Gun 2: "Well, it looks like the cows have come home to roost!"

From the first Austin Powers film: "But unfortunately for yours truly, that train had sailed."

Mr. Furious from Mystery Men does this a lot, often in conjunction with Metaphorgotten. "I don't need a compass to show me which way the wind shines."

In The Movie of Master and Commander, the entire final battle hinges on a tactical maneuver Captain Aubrey derives by completely mangling the notion of an insect that disguises itself as a stick to evade predators.

Captain Aubrey: Now to pull this predator in close and spring our trap.

Literature

Lampshaded in The Stainless Steel Rat's Revenge: Inskipp says they "must get a man to Cliaand to root out the problem at the core of the woodpile and cut the Gordian knot." Slippery Jim replies, "Other than being contained in a mixed and disgusting metaphor I think the idea is a suicidal one."

Happens constantly in the Aubrey-Maturin books. Usually in the form of Jack mixing a metaphor, Stephen "helpfully" correcting him, and Jack becoming even more confused. To wit...

'Why, as to that,' said Jack, blowing on his coffee-cup and staring out of the stern-window at the harbour, 'as to that ... if you do not choose to call him a pragmatical clinchpoop and kick his breech, which you might think ungenteel, perhaps you could tell him to judge the pudding by its fruit.'

'You mean, prove the tree by its eating.'

'No, no, Stephen, you are quite out: eating a tree would prove nothing.'

Used a lot in Discworld, primarily by Mustrum Ridcully and Nanny Ogg - example from the latter "The worm is on the other foot now!" (mixing 'the worm has turned' with 'the boot is on the other foot now').

The troll Ed in the book Once Upon A Marigold is fond of mixed metaphors, such as "Let's get this show on the ball" and "He'd buttered his bread, and now he had to lie in it."

In Stephen Colbert's book I Am America (And So Can You!), the character admits that he's "not the smartest knife in the spoon."

This is one of the things that George Orwell criticizes in his famous essay "Politics and the English Language." His most famous example (presumably made up) is The fascist octopus has sung his swan song.

Dave Barry likes to mix his metaphors. One impressive example: Dave Barry Slept Here describes the Great Crash of 1929 as the day when "the nation's seemingly prosperous economy was revealed to be merely a paper tiger with feet of clay living in a straw house of cards that had cried 'wolf' once too often."

Poul Anderson's Technic History: Nicholas Van Rijn, along with malapropisms, often mixed metaphors. Particularly appealing was his reference to forcefully seeking something he wanted "like a bulldozer going after a cowdozer."

Lampshaded in Dirk Gently's Holistic Detective Agency, after Michael Wenton-Weakes's mother is described as a battle-axe: "She had been waiting patiently -- or at least with the appearance of patience -- in the wings all this time, being the devoted wife, the doting but strict mother. Now someone had taken her -- to switch metaphors for a moment -- out of her scabbard and everyone was running for cover."

In A Song of Ice and Fire, the spymaster Varys is known as the Spider, but his spies are called his "little birds."

Live Action TV

The Mayor on Buffy the Vampire Slayer: "This year is too important to let a loose cannon rock the boat. Loose cannon. Rock the boat. Is that a mixed metaphor? Boats did have cannons. And a loose one would cause it to rock."

Sir Desmond: If you spill the beans, you open up a whole can of worms. How can you let sleeping dogs lie, if you let the cat out of the bag? Bring in a new broom, and if you're not careful, you'll find you've thrown the baby out with the bath water. If you change horses in the middle of the stream, next thing you know you're up the creek without a paddle.

After Chris' death in the sixth season of The Sopranos, Tony has to dispel a rumor that he killed him (he did so as a mercy killing after a car crash). He starts off by saying, "Okay, we gotta deal with the 500-pound elephant in the room..."

Nina from Just Shoot Me: "A bird in the hand is worth two if by sea" and "Denial is not just a river in England."

Magda from Brazilian sitcom Sai de Baixo, being from the ditzy kind of stupid, has some of these such as "Who plants the wind, reaps blood, sweat and beers" and "everyone in life must plant a son, have a book and write a tree!".

Cyril Bryson on Chef "This is the eye of the needle that breaks the camel's back!"

The Seventh Doctor on Doctor Who started out doing this a lot. "A bird in the hand keep the doctor away." "A memory like a kangaroo." "Time and tides melt the snowman." It was initially intended to be a consistent quirk but, after he'd come to grips with himself, he (or rather, the writers) grew out of it.

People forget that the Fourth Doctor did it too (just never in such a high concentration). "While there's life, there's six of one, half a dozen of the other."

"Ryan is now at corporate where he is a little fish in a big pond. Here, I am still top dog. So which is better... being a dog, or a fish?"

Serena on Gossip Girl talks about how her mother adapts to each new husband:

Serena: The second he starts to call the shots these gloves come off and the nails come out. I just mixed metaphors, didn't I?

One of El Chapulin Colorado's trademark gags: every time he tries to cite a famous saying he gets it mixed with another one, and ends up saying "...Well, you get the idea."

Lampshaded on Mad Men when Bert Cooper calls Don in to tell him they can't fire Pete Campbell because his family is too old and important. He starts off about how New York City is like a fine watch full of tiny, precise parts and always ticking away. Don says it sounds more like a bomb. Cooper says that if they fire Pete word will get around to the Dykeman-Campbells' million connections around the city and the agency will lose some of its establishment cred, and when Don objects to this kind of nepotism, Cooper tells him, "You'll have to have a stronger stomach if you want to be back in the kitchen seeing how the sausage is made." Don, after a beat: "I thought it was a big watch."

In The Thin Blue Line episode "Night Shift", Inspector Grim informs everyone that he is looking for:

On True Blood Jason is famous for these "If a tree falls in the woods and no one is around to hear it, it's still a tree isn't it!"

Magazines

The New Yorker often fills up extra space at the end of an article with a short excerpt from another publication, filed under "Block That Metaphor!" if it fits this trope. ("The moment that you walk into the bowels of the armpit of the cesspool of crime, you immediately cringe.")

Mixed metaphors are one of the richest veins for the sports-commentator gaffes that Private Eye refers to as "Colemanballs".

Music

This was part of what made Elton John's Princess Diana version of "Candle in the Wind" so notorious. She's a candle, but she's also a rose and a golden child, capable of leaving footprints on England's green hills, plus equipped with wings of compassion. Cause of death was wind, rain, and/or the fading of the sunset.

Kathy Mattea's "Clown in Your Rodeo" completely derails its rodeo metaphors in the second verse:

Hand me my feather duster

I'm cleaning house out of the gate

Before my heart starts caving in

Kenny Chesney's "Better as a Memory" has a verse that starts out with "Goodbyes are like a roulette wheel" and ends with "You're left holding a losing hand".

Martina McBride's "Ride" has "Life is a roller coaster ride / Time turns the wheel and love collides." Wait, what?

The second and third verses of "Run-Around" by Blues Traveler are constant strings of these.

In an episode of Unnatural Acts, Jeremy takes various mixed medicines, with predictably spaced-out results. His speech pattern changes to reflect this, with mixed metaphors being one of the symptoms.

Jeremy: Blast! I knew I shouldn't have tried to rub elbows with the small potatoes when I should be chewing the cud with the big fish!

In Hamish And Dougal, Dougal taunts the Laird with "Hah! So you don't like it when the boots are down and the chips are on the other foot!"

Theater

Older Than Steam: Hamlet: "Whether 'tis nobler in the mind to suffer the slings and arrows of outrageous fortune, or to take arms against a sea of troubles, and by opposing end them?" Apparently, Shakespeare was notorious for this. Then again, Hamlet was probably Schizophrenic.

TV Tropes

All-Devouring Black Hole All Devouring Black Hole Loan Sharks, the trope title. Sharks and black holes both have a well-deserved reputation for devouring and destruction--but surely they don't have anything else in common. Perhaps this status as a mixed metaphor is one reason why the "all-devouring black hole" part is now a mere alternate title for the trope, but it could be argued that this makes the trope more fun since comparing anything to a black hole is a very colorful metaphor.

Web Comics

Haley Starshine: "If you want to pull the strings, you've got to pay the piper!"

Homer: They ran away like schoolgirls with their tails between their legs!

In Ben 10: Alien Force: Rath's food is accidentally blown away by Octagon Vreedle, prompting Rath to say "A man's food is his castle!" (Octagon calls him out on it, using the page title).

Real Life

There is a famous quote from the time of king Louis-Philippe of France: "Le char de l'État navigue sur un volcan!" (The chariot of the State is sailing on a volcano!) Chariots can't sail, especially on volcanoes...

A few years ago, this quote from a participant in a symposium about AIDS: "We are sitting on a volcano and running toward disaster!" Here, the translator may be to blame. Or else they were doing that russian sitting dance...

From a Newt Gingrich press release:

The literati sent out their minions to do their bidding. Washington cannot tolerate threats from outsiders who might disrupt their comfortable world. The firefight started when the cowardly sensed weakness. They fired timidly at first, then the sheep not wanting to be dropped from the establishment’s cocktail party invite list unloaded their entire clip, firing without taking aim their distortions and falsehoods. Now they are left exposed by their bylines and handles. But surely they had killed him off. This is the way it always worked. A lesser person could not have survived the first few minutes of the onslaught. But out of the billowing smoke and dust of tweets and trivia emerged Gingrich, once again ready to lead those who won’t be intimated by the political elite and are ready to take on the challenges America faces.
